Potentially the chips will function like biological synapses making them ideal for many artificial intelligence applications. The memristor is basically an electrical resistor with memory properties. This discovery may make it possible to fashion advanced logic circuits known as filed programmable gate arrays. These are widely used for rapid prototyping of new circuits and for custom made chips that need to be created quickly.
The original memristor was written about in a a research paper done by a Berkeley electrical engineer named Leon Chua in 1971. His paper titled “Memristor - The Missing Circuit Element” argued that basic electronic theory required that in addition to the three basic elements - resistors, capacitors, and inductors - there is a fourth element that should exist, the memristor. And the HP team created working circuits based on memristors that are as small as 15 nanometers, but they believe that they will be able to make one as small as 4 nanometers.

memristor (so-called because it is part memory, part resistor)

But in a memory resistor, the hose remembers what direction the water (or current) is flowing from, and it expands in that direction to improve the flow. If water or current flows from the other direction, the hose shrinks.In the limiting case you have a diode that permits current flow in one direction and not in the other. The "memristor" sounds like a "leaky" diode or a diode with a resistor in parallel to model the backward direction. I'm not convinced it is much of a "breakthrough".

All this, combined with the “dumbing down of America”, and artificial intelligence won’t need to be too smart to outsmart most of us.
Can an AI “lifeform” be far off now?

The hose analogy makes it sound more like a ‘memductor’ than a ‘memristor’.

Not sure I like that idea...
Windows crashed again!
Dang, can't move the mouse, gotta reboot...

Aw, Sh**!

It’s not a diode. A diode has ‘baked’ into it which direction it has lower resistance. A memristor is an easily reversible diode — a touch of current on one line, and it reverses; a touch of current on the other line, and it reverses the other way.

Sounds like a pretty new term for hysteresis.

Potentially the chips will function like biological synapses making them ideal for many artificial intelligence applications. For 20 years, we've been able to get the same transfer characteristic as in a synapse by going into the deep subthreshold domain of transistor operation.
I want to see the i, v, and t differential equations for this "menristor" thing-a-ma-doo-dad before commenting on it....

Kind of nice to see pioneer HP back at the front lines of technology.

Mark my words. This will have more impact than anything else in the next century.

But only thanks to Microsoft, which has ensured that billions of man-hours are wasted annually for computers to boot up.

It sounds more like a leaky flip-flop. (Although those are level-sensed and not current sensed).

Mark my words. This will have more impact than anything else in the next century.I, for one, believe you are correct. A theoretical advance that has been around for 40 years before realization is a great indicator of future worth.

Yes - I think so. Though (1) I'm not sure why you say "leaky" (I haven't noticed any claims that the device "leaks" state over time), and (2) it's
substantially smaller in size and power needs than a
single transistor, whereas a flip-flop requires five or ten transistors (I'm not sure exactly), and (3) it keeps state while powered entirely off.

Consider that the description of the device was filtered through a reporter.
I sincerely doubt that a reporter could adequately describe the functioning of a capacitor or an inductor, much less a new class of device.
